As “Doctor Who” fans celebrate the series’ 50th anniversary this year, anticipation is building to the special anniversary episode, “The Day of the Doctor,” set to premiere Saturday, November 23. Today, the BBC has debuted a special poster design for the 75-minute adventure. Check it out below!

“The Day of the Doctor” stars Matt Smith (How to Catch a Monster), David Tennant (“Broadchurch”), Jenna Coleman (“Dancing on the Edge”), with Billie Piper (“Secret Diary of a Call Girl”) and John Hurt (Tinker Tailor Soldier Spy). This is the first time Tennant and Piper have appeared in the series since their farewells in 2010.

“’The Day of the Doctor’ is nearly here!” says Smith. “Hope you all enjoy. There’s lots more coming your way, as the countdown to the 50th begins now.”

“50 years has turned Doctor Who from a television show into a cultural landmark,” says Steven Moffat, lead writer and executive producer. “Personally I can’t wait to see what it becomes after a hundred.”
